How to achieve this result in an image in PS elements 2021 or PSCS6?

Hello mimigull A warm welcome to the forum. What you have to do to achieve this edit is first extract your subject from the background of the image.
To do this click on Select at the top of your screen and from the drop down menu select ‘Subject’ and then you will see what we call the marching ants surround the edges of your subject - in this case - the young lady. I would then click on Select again and this time I would choose ‘Feather’ and from the dialogue box that appears I would type in 1 or maybe 2 click ok and then while holding down the Ctrl key on your keyboard press the letter j and this will copy the extracted image to a layer on it’s own in the layers panel.
You can then place the extracted image on whatever background you choose.
I see from the example you have shown that there is soft edges round the ladies jumper at the bottom. To do that create a layer mask on the same layer as the extraction (example) and with the layer mask selected and using a soft black brush with black as the colour brush carefully around the edges of the lady as shown.
I hope this helps.

Hi mimigull .   Lillias has demonstrated how you can extract your person.   Being we are a learning forum, if you wanted to, you could add a full sized image to the The Member to Member Advice board. 

I found two tutorials that might possibly help you.  It seems that the oil painting filter was introduced in PSCS6 so you may find these YouTube videos helpful.

Actually, I should have asked two questions. 1) How did they get this image in focus so well? 2) How did they get the final effect? Is this the oil paint filter or something else? The final image is so smooth. Thanks to all who responded, your guidance is greatly appreciated.

As you can see above, there are a few ways you can do this.

I like to use layer masks as they give me more flexibility so I would do something along this line.  The selection to create the layer mask would need to be tidied up a bit though.

1.  Place the original image with its background on a blank black canvas - new document. (portrait-left)

2.  Duplicate the original image and create a layer mask to display just the person (portrait-right).  You can move the portrait-right layer wherever you like using the Move tool and the layer mask will follow since it is locked to the image by default.

3.  Use a soft black coloured brush on the layer mask to create the soft curved edge along the base of portrait-right.

4.  Duplicate portrait-right and blur it.

5.  Use a black brush on the layer mask to apply the blurring to just the chest area to suit.

Hope this helps and good luck :-)








Regarding your Q1, they probably used a tripod and a reasonably fast shutter speed to freeze any subject movement.
